 그 외의 지수는?
 어떤 모델이 지금의 현상을 가장 잘 설명하는다고 판단하는가?
+  * Model fit
+    * Chi-square Test: p-value less than p-critical value (.05 for example) indicates that model does not fit well enough. p-value more than critical value means the model fits the data relatively well. The test is sensitive to the sample size and normality of the data.
+    * CFI (Comparative Fit Index): greater than .90 indicates good fit to the data. It is less sensitive to the sample size and normality of the data than chi-square test.
+    * TLI (Tucker-Lewis Index): greater than .95 (sometimes .90) indicates good fit. It is less sensitive to the sample size.
+    * RMSEA (Root Mean Square Error of Approximation): equal to or less than .08 (sometimes .10 is used) indicates good fit to the data.
+    * SRMR (Standard Root Mean square Residual): less than or equal to .08 indicates good fit to the data.
